YAMAHA YST-SW1500

Commentary

An active subwoofer developed as a flagship model.

The unit is equipped with 30 cm cone type woofer.
This unit uses a dual-bias magnetic circuit, in which two pairs of opposing magnets provide uniform and cooperative magnetic flux density.
In addition, an aluminum die cast frame is used for the frame.

QD-Bass technology is adopted.
In this system, the woofer unit is installed downward and a pyramidal diffuser plate is installed on the bottom to efficiently radiate low-temperature energy in four horizontal directions. This realizes smooth frequency characteristics and free setting regardless of installation location.

The enclosure uses the Advanced Yamaha Active Serve Technology (A-YST) system.
Based on the concept of an air woofer that uses air itself as a diaphragm, the A-YST system enables low-frequency playback equivalent to that of a large speaker even in a small enclosure.
The exterior has a cherry finish.

The amplifier section is equipped with a 1 kw high-efficiency power amplifier.
Also, a high-efficiency power source is used for the power supply.

Equipped with LFE input.

Equipped with an auto standby function.

Equipped with a B. A. S. S. mode switch.
Movie/Music can be switched, and low sound playback is possible depending on the source.

Equipped with a phase selector switch.

Wireless remote controller with 3-position memory function is included.
